DEFINITION

Classification: 264/122

(under subclass 109) Processes involving the use of (1) two or more kinds of particles differing in composition or (2) particles of the same composition but disclosed to be of different particle sizes.

(1) Note. Where particles of different composition are employed, these may bond autogenously at their surfaces, a liquid binder or adhesive may be used or one of the kinds of particles may act as a binder by, for example, losing its identity as a particle by melting and flowing about or between the remaining solid particles.

(2) Note. Where different sizes of particles of similar composition are employed, said difference in size of the particles must be set out, since it is understood that normally in particles handled in mass or bulk, there will be minute differences in particle size although the overall appearance thereof would indicate homogeneity.
